HENRY L. KA'UFMANN, 0F EWTOKM'MASSACHUSETTS PAIL PROTECTOR Applicationled September .13, 1930. Serial No. 481,705.

This invention relates to a cushioning protector for the basis of pails,buckets or other receptacles, and has forits principal object theprovision of a simple and economical .s device of resilientfmaterial,which may be removably secured at the bottom portion of an ordinary pailwithout'special fastenings and which serves not only to protect thepaill and the ioor or platform upon which it rests 1U from beingchipped, scratched or marred through mutual contact, `but also to deadenthe sound and disturbance commonly caused when an unprotected pail isdeposited or movedv about upon a Ihard-surfaced floor,

is table, or other support.

The vimproved protector is particularly adapted as a cushioning deviceor silencer upon pails used in the operating-roomsof 'hospitals or undersimilar conditionswhere 2u the absence of distracting noises isessential to proper concentration. The article may, however, be employedgenerally to protect the pail and its supporting surface fromdamage, andit may be fitted to buckets, cans or other receptacles whose shape andsize may vary within wide limits. f

recommended embodiment of the invention is illustrated inI theaccompanying drawing in association with around pai 30 having slopingsides, but its applica-tion to 'receptacles of other shapeswill beapparent.

t In the drawing 1 a Fig. 1 is a side elevation of the pail equippedwith the improved protector; r Fig. 2 is `a perspective view of theprotector; and

Figs. 3 and 4 are enlarged radial sections of an 2respectively.

In the particular embodiment chosen for the purpose of illustration, theprotector com-` prises a substantially cylindrical sleeve yor bodyportion 5 of rubber or other resilient material, and a'ilexible andresilient, ringi like base portion 6 substantiall y thicker than ,thesleeve portion to furnis an interior lannular ledge or shoulder 7 `Thesleeve 5 is adapted, upon being expanded, to receive the bottom portionof the pail 8 and,` upon contraction, to embrace the pail and hencesecure the a sheet of vulcanized rub used in automobile tires, and therubber base)` ad p x ring 11 may be produced from a rubber'cylinortionsofthe articles shown in Figs. 1-

protector therein, withthe pep riphery of the pail bottom 9 Vseatingupon the shoulder 7 of the protector.

As shown in Figs. 3 and 4, the thickened base portion 6vof Figs. 1 and 2may be formed 55' by doubling the lower portion 10 of the sleeve over alrubber base ring or core 11 and cementing the folded margln upon theinner face of the\sleeve as at l2. It will be observed that a protectorbottom, thereby reducing the cost of manu-v facture, as compared withthe expense of producing a protector having a closed bottom, andproviding a more sanitary protector, for it is apparent that anyliquids, 35' dirt, or'othermattenwhich may passdownwardly bet-Ween thesleeve and the pail will drop throughfthe open' ring instead ofcollectlng at the bottom of the protector.

An article constructed asabove described "0 may be readily applied to orremoved from the pail, it is durable, inuse and fulfills its intendedpurposes" without adding Aappreciably to` the weight of the pail ordetracting from its normal use or appearance; and ,it 75` may beconstructed at little expense from common materials. For example, thesleeve portion 5 of the protectorgnay be made from er, similar to thatder or tube which may have an axial reinforce,`

13 of metal, such as is used in making tires for velocipedes, infantscarriages or the like. A

The endsf of the core 11 may be joined in ac- 35' cordance with commonpractice by connecting the ends of the wire 13, and the lower portionofthe sheet may be wrapped around the ring 11 and fastened upon thelnner` surface .of the sleeve by' a suitable cement or other securing9o'.

means. j Owing to lthe liexibility of the base ring and its sleeve theprotector may easily be shapedto fit the bottom'of a polygonal pail,

if desired; and its adaptation to other recep- 9'5` tacles is obvious.The diameter of the sleeve should ordinarily be less than that of the'ail,

but in case the pail has sloping sides the s eeve ma have th'e`. samediameter as the 'ailbase if It will be observed that'the sleeve 100 thusformed is open at the e0 disclosure is for the purpose of 5 extends asubstantial distance upwardly from the base of the pail, therebyprotecting the sides of the pail from against kicks or other impactswhile the pail is in use or while it is being emptied over the edge of asink or other receptacle.1 A

It should be understood that the present illustration only and that thisinvention includes all modifications and equivalents which within thescope of the appended claims.

I claim 1. A protector for application to the bottom portion of a pailcomprising a sleeve portion of sheet rubberfand a base ring larger incross-section 'than sleeve, the base ring consisting of a rubber coreand the lower margin of the sleeve being doubled around the ring andsecured to the v inner surface of the sleeve.

2. A protector forl application to the bot# tom portion of a pail,comprising a sleeve portion of sheet rubber, and a base Iring larger incross-section than the thickness of the sleeve, the base ring consistingof a rubber core and the lower margin of the sleeve being doubled aroundthe ring and secured to inner surface of the sleeve, the sleeve portionextending upwardly a substantial distance .over'the sides of thereceptacle thereby to protect the sides from impacts.

3. A protector'for application tothe bottom of a ail, comprising asleeve portion of sheet rubber adapted to receive and embrace the bottomof the pail, and

cross-section'than the sleeve the base ring being embraced by the lowermargin of the sleeve and permanently attached thereto thereby to providean interior annular` constituting a seat for the pail bottom, and

`the sleeve portionextending upwardly a substantial distance from thebase ring to protect 4 i. the sides of the pail from impacts.
